Unidirectional Units

D2 W LT (transmitter)
D2 W LR (receiver)

The unidirectional wireless range of products is suitable for connecting to a single sensor or group of sensors and provides an economical solution for remote monitoring systems. The unidirectional products can also be used in more complex networks such as signal transmitters or receivers.

Applications

• Wireless connection of flowmeters or energy meters
• Monitoring of storage tanks
• Monitoring cathodic protection on pipelines
• Wireless alarms from power reticulation fault-relays

Features

• Up to 5 intermediate transceiver units can be configured to link inputs or outputs to transmitters or receivers
• Factory configured as a matched transmitter/receiver pair or user-configurable with E-Series Windows configuration program

Transmitter Unit

• Class I, Division 2 hazardous areas approved (USA/Canada); (CSA certified)
• Input-only transmitter unit, two digital/pulse inputs, one analog input, and one thermocouple mV input
• Transmits to receiver unit as a matched pair where the input signals are re-created as output signals or can transmit to a transceiver or gateway unit
• Up to 3000 wireless transmitters can be used in a network (255 inputs can be linked to any radio unit address)
• External inputs plus internally calculated values, including analog set-point status, pulse count, power supply voltage
• Thermocouple input –10 to +100mV with cold-junction compensation and linearization for J, K, or T-type
• Set-point status generated by comparing analog input to high and low set-points
• Digital inputs can also be used as pulse count inputs
• Power supply 9 – 30VDC, measured and available as a transmitted variable
• 24VDC analog loop supply internally provided
• RS232 configuration and diagnostics port
• RS232 - RJ45 cable required for setup (catalog number: CBLSER RJ45)

Receiver Unit

• Class I, Division 2 hazardous areas approved (USA/Canada); (CSA certified)
• Output-only receiver unit, three digital contact outputs, and one analog output
• Receives radio commands from transmitter unit as a matched pair where the input signals are re-created as output signals, or can receive commands from a transceiver or gateway unit
• Up to 3000 wireless receivers can be used in a network (255 inputs can be linked to any radio unit address)
• Power supply 9 – 30VDC; 24VDC analog loop supply internally provided
• Communications failure indication and configurable output
• Outputs can be configured as retained or reset (failsafe) on communications failure
• LED indication of radio signal strength
• RS232 configuration and diagnostics port
• RS232 - RJ45 cable required for setup (catalog number: CBLSER RJ45)
